* The additional measures listed in the table are minimum measures under consideration of Table 1 in the pamphlet on sub-roofs, sub-coverings and under-bracings. Sub-covering panels are to be assigned according to the classification in the pamphlet on sub-roofs, sub-coverings and under-bracings. Increased demands make up categories according to chapter 1.1.3. Further increased demands can arise out of the weighting within a category according to 1.1.3. For example, climate situations can result in several increased demands. Only permitted if the manufacturer provides proof of the functionality and safety of the products used, including accessories (sealing tapes, sticky tapes, sealing compounds, pre-assembled seam securing, etc.), as part of a deluge test and 24-hour rain test on a roof pitch of 15°. Otherwise, the next class up is to be selected. Any limitations noted by the manufacturer are to be taken into account. See the product data information sheet for instructions regarding protection against perforation. These can be used for classes 3 to 6.

2001: Ergoldsbacher Forma®

A clever connection between design and economy

The Ergoldsbacher Forma® is characterised by its soft, well-proportioned shape, which is distinctive and the only one of its kind on the market. This designer roof tile particularly complements modern architecture, and lends renovated buildings a very individual appearance as well thanks to its lovely colours. Like all Ergoldsbacher roof tiles from the 38,5 cm gauge class, this flat roof tile can be laid very quickly, and is ideally suited to tented and hip roofs due to its low profile.

Quantity required per m²: from 9.9 Pieces

Minimum roof pitch: 10 °

Regular roof pitch: 22 °
